USING THIS GUIDE
To fully appreciate the capability of the HFA II and develop good testing techniques, we
recommend that you rely on the User’s Guide as your training and reference manual. It has
been designed to make learning easy. The concise step-by-step instructions and accompanying
illustrations help you get started quickly and with more confidence.
We think you will enjoy working with the HFA II. The friendly touch control makes it inviting to
learn and easy to operate. For optimum results:
• Read your guide in the order written.
• Read it while sitting at the instrument.
• Practice using the HFA II by first testing staff members before using it with patients.
Model differentiation This guide contains instructions for Models 720i, 740i, 745i and 750i. Although much of the
information is relevant to all models, some information only applies to particular models.
When a feature or function applies to specific models, this guide specifies the model
number(s), often in parentheses, in a prominent location. An example of this is found in the
previous discussion of Blue-Yellow testing (previous page). Conversely, model numbers are
not specified when information is standard or optional on all models.
You can find the model number of your instrument on the rear panel of the HFA II or you may
access this information via the “
i ” button located in the upper, left-hand corner of the screen
(see Section 2: “The Information “ i ” Button”). If you are unsure about the particular
capabilities of your instrument, refer to Appendix A: “HFA II Product Specifications”.
Text conventions The terms “select,” “choose,” and “press” are used interchangeably. Each term means to
initiate an operator action using the touch screen, external keyboard, trackball, or mouse. The
terms “hard disk” and “hard drive” are used interchangeably in reference to the data storage
device standard on all HFA II models.
UPPER CASE LETTERS are reserved for references to specific command buttons found on the
touch screen. The exceptions to this are messages on test printouts, the words STATPAC, SITA,
SWAP, HFA II, and headings.
Italicized words are used to identify the icon buttons on the right border of the screen, the
titles of figures, pictures, tables, and special notes in this manual.
Bold words are used to highlight warnings and section headings.
Additional references The User Guide cannot possibly cover every situation you may encounter with the HFA II,
especially interpretation questions. Your HFA II comes with a copy of
The Field Analyzer
Primer which provides an overview of visual field results. Automated Static Perimetry,
Second Edition , by Douglas R. Anderson and Vincent Michael Patella (Mosby, Inc., St. Louis),
is recommended for in-depth information and analysis of visual fields.
